The cut side gets exposed do the oxygen in the air and starts to react. Polyphenols are oxidised by oxygen from air when the 'polyphenol oxidase' enzyme is freed after cellular disruption (damage).
So the browning of cut apples is oxidation - the same as rust. Potatoes, apples and avocados to name a few do it. if you squeeze lemon juice on avocados, and put potatoes and apples in acidulated water (water with lemon juice) they won't oxidize.
A different thought...
It rots. The apple has been decomposed. So the answer would be decomposition.
